 ====== Acquiring Digital Codes ======
-It is critical that we acquiring stimulus-locked digital codes so that we can bin the data according to stimulus type during analysis. This is also essential for creating event-related averages of the psychophysiological data (e.g. creating ERPs from EEG data) as it gives us the precise onset time of each stimulus. Below is a description of the hardware, software, and steps necessary for sending and acquiring such codes using the Biopac MP150.

 The LabJack U3 can be controlled via several different programs and languages. We use the [[http://labjack.com/support/labjackpython|LabJack Python module]] to send codes via [[http://www.psychopy.org/|PsychoPy]].
-To date, I have only had success controlling the LabJack from a computer running the Mavericks OS (not Yosemite). The computer should have [[https://developer.apple.com/xcode/|Xcode]] (including the **Command Line Tools**) installed. The libusb package should also be installed (see [[http://labjack.com/support/linux-and-mac-os-x-drivers|here]] for details). Finally, the [[http://labjack.com/support/linux-and-mac-os-x-drivers|LabJack exodriver]] and [[http://labjack.com/support/labjackpython|LabJack Python module]] should be installed.
